Product Details


Product Description

This Boston Gear PA series timing pulley is made of aluminum, has a 3 mm pitch, and is suitable for use with 6 mm wide curvilinear tooth belts in power transmission applications that require synchronous rotation. This pulley has a 0.250" bore diameter and mounts to a drive shaft using setscrews. This flangeless pulley is used where belt side thrust is not an issue, and the clear anodized aluminum construction provides light weight and corrosion resistance. Timing pulleys are a type of drive pulley and are used in a wide range of mechanical and electronic drives, including automotive and printing industries.

Pulley drive systems consist of two or more pulleys that connect with a belt to transmit mechanical power across greater distances than systems that use gears. Pulleys (sheaves) are available in different types: V-belt, timing, round, or flat. Pulleys must match the belts that connect them (timing pulleys with trapezoidal grooves require a belt with trapezoidal teeth) and engage either on the sides of the pulley flange (classical V-belts, narrow V-belts, or round belts), on the flat outer diameter of the pulley (flat belts), or in pulley grooves that match belt teeth (timing belts, synchronous belts, or curvilinear belts). Pulleys are made of various materials, including cast iron, steel, aluminum, polycarbonate resin thermoplastic, and nylon, and they can meet a broad range of requirements, including increased torque, resistance to wear, and light weight. Pulleys are used in drive designs in the automotive, appliance, agriculture, textile, printing, mining, and office equipment industries.

Boston Gear manufactures gears, gear drives, bearings, valves, shaft collars, couplings, and other power and fluid transmission components. The company, founded in 1877, is headquartered in Charlotte, NC, and meets International Organization for Standardization (ISO) standard 9001:2008 standard.
